BACKGROUND OF THE INVENTION
The present invention relates to a faucet column installed in a garden or a park.
[0002]
[Background Art and Problems to be Solved by the Invention]
For example, a faucet column has been used as an outdoor water supply means such as a garden or a park. However, there are many cases where hot water is required instead of water outdoors. For example, hot water is preferable to water when washing a car outdoors or washing hands in winter. However, there has never been a faucet column that can discharge hot water in addition to water.
[0003]
An object of the present invention is to provide a faucet column that can discharge hot water in addition to water in a garden or a park.
[0004]
[Means for Solving the Problems]
The above-mentioned purpose is to provide a water supply riser whose lower end is connected to a water supply pipe, a hot water riser whose lower end is connected to a hot water supply pipe, a hollow columnar casing in which a compatible upflow pipe is built in parallel, and an upper end of the casing. And a mixing faucet column according to the present invention comprising a mixing faucet provided at the top and connected to the upper end of the compatible up-tube.
[0005]
That is, if the mixing faucet column is installed in a garden or a park, water and hot water can be selectively discharged from the mixing faucet provided at the upper end of the casing as needed. it can.
[0006]
The mixing faucet column according to the present invention may further include a branch faucet provided on one side of the casing so as to communicate with the middle portion of the length of the water supply riser pipe.
[0007]
If the mixing faucet column is further equipped with a branch faucet as described above, for example, the branch faucet can be used exclusively for a hose with a hose connected to it, and the mixing faucet can be used free of charge. Improves. The height at which the branch faucet is provided is not particularly limited, but when it is dedicated to the hose as described above, for example, it is provided at such a height that the distance to the hose reel placed on the ground is as short as possible. Is preferred.
[0008]
In the above-described mixed faucet column according to the present invention, instead of the hot water riser pipe whose lower end is connected to the hot water supply pipe, it has an underground hot water supply pipe connection part at the lower end part, and a hot water pipe arranged above the ground at the middle part of the length. A hot water riser pipe having a connection portion may be provided, one of the connection portions being connected to a corresponding hot water supply pipe, and the other outer end opening being closed by a lid.
[0009]
If the mixing faucet column is equipped with a hot water riser pipe having the two hot water pipe connecting parts as described above, the hot water pipe that runs from the hot water source such as a water heater to the installation location of the mixed faucet column is underground. It is possible to easily cope with both the case where the pipe is embedded and the case where the pipe is disposed on the ground. Especially in the latter case, it is not necessary to embed a hot water supply pipe underground, and the burden of piping work is reduced accordingly, so for example when installing a mixed faucet column instead of an existing faucet column. It can be advantageously applied.

It may be. The cross-sectional shape of the casing can be, for example, a circle or a square. Moreover, you may make it provide in the casing the space for interposing insulating materials, such as hard foamed resin, between a casing and a compatible upflow pipe.
[0016]
There are cases where the water supply pipe to which the water supply riser pipe is connected and the hot water supply pipe to which the hot water supply riser pipe is connected are buried in the ground and arranged on the ground, respectively. When at least one of the compatible upstream pipes is connected to a water supply pipe or a hot water supply pipe embedded in the ground, the casing is erected on the ground by having its lower end side buried in the ground for a required length. On the other hand, when the compatible up pipe is connected to a water supply pipe and a hot water supply pipe respectively arranged on the ground, the casing is placed on the ground by having its lower end side buried in the ground for a required length, and the casing The lower end portion is supported and fixed to a support base placed on the ground, or the casing lower end portion is provided integrally with the same portion and supported by outward projecting support legs placed on the ground, In some cases, it can stand up on the ground.
[0017]
The lower end of the water supply riser pipe and the water supply pipe, and the lower end of the hot water supply riser pipe and the hot water supply pipe are usually connected via an L-shaped joint such as an elbow. In this case, a communication hole is made in the casing portion corresponding to the outer end opening of both L-shaped pipe joints. Preferably, the outer end portion of the L-shaped joint is fixed to the peripheral edge portion of the communication hole in the casing by using, for example, a fixing metal fitting having a screw or a female screw. In addition, at least one of the lower end of the water supply riser and the water supply pipe, and the lower end of the hot water supply riser and the hot water supply pipe is connected via a straight pipe joint such as a socket instead of the L-shaped pipe joint. You may make it do.
[0018]
As a mixing faucet provided in the upper end part of a casing, a single lever type etc. may be used besides a 2 handle type. In the mixing faucet, the faucet body is housed in the upper end of the casing, and the water faucet and the handle or lever protrude outside the casing. May be externally attached.
